Enthalpy change for oxidation of glucose:
The enthalpy change for the oxidation of glucose is given as 28880 kJ/mol. This value represents the energy released when one mole of glucose is completely oxidized.
Utilization of energy by body muscle:
According to the problem, 25% of the energy produced during the oxidation of glucose is utilized by the body's muscles. This means that only a fraction of the total energy is actually used for performing work.
Energy required to work for 1 km:
To determine the distance a man can walk by consuming 120g of glucose, we need to know the energy required to walk a certain distance. It is given that 100 kJ of energy is required to work for 1 km.
Calculating the energy available from 120g of glucose:
To calculate the energy available from 120g of glucose, we need to convert the mass of glucose to moles. The molar mass of glucose is approximately 180 g/mol. Therefore, 120g of glucose is equal to (120/180) = 0.67 mol.
The energy available from the oxidation of glucose can be calculated by multiplying the enthalpy change by the number of moles of glucose:
Energy available = 0.67 mol * 28880 kJ/mol = 19323.6 kJ
Calculating the distance:
Now, we can determine the distance a man can walk by dividing the available energy by the energy required to work for 1 km:
Distance = 19323.6 kJ / 100 kJ/km = 193.24 km
Therefore, a man can walk approximately 193.24 km by consuming 120g of glucose.
Summary:
- The enthalpy change for the oxidation of glucose is 28880 kJ/mol.
- Only 25% of this energy is utilized by the body's muscles.
- It is given that 100 kJ of energy is required to work for 1 km.
- By consuming 120g of glucose, the available energy is calculated to be 19323.6 kJ.
- Dividing this energy by the energy required per km gives a distance of 193.24 km.
